LOOM.

To all whom it may concern Be it known that I, ANDREW BROWNING, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Looms, of which the following is a specification.

For the purpose of lubricating car axles the use of yarn waste in the journal boxes is rapidly being superseded by the use of suitable woven fabrics. To be useful for such purpose, the fabric must have a cut pile face for bearing against the axle and applying lubricant thereto, and it must be provided with depending streamers or tails which will act as wicks to draw up the lubricant from the bottom of the journal box so that it will reach the axle, and the object of my invention is, to provide a loom upon which a fabric of this type may be woven.

This object I accomplish in the manner hereinafter set forth, reference being had to the accompanying drawing, in which Figure 1 is a diagrammatic sectional view of a fabric such as my improved loom is intended to produce.

Fig. 2 is a vertical sectional view of sulficient of the loom to illustrate how such a fabric is woven;

Fig. 3 is a plan view, on a larger scale than Fig. 2, of certain portions of the loom, and

Fig. 4 is a vertical sectional view of the loom parts shown in Fig. 3.

Referring in the first instance to Fig. 1, I have shown the fabric as woven of warp threads 1, binder threads 2 and 3 and Weft threads 4. At intervals, a loop of the warp thread 1 is drawn out beyond the back of the fabric, as at 1 It is these loops 1 that act as wicks when a section of this fabric is being used as an axle lubricator.

The loom construction which enables me to weave the fabric shown in Fig. 1, I have shown in Figs. 2, 3 and 4. In Fig. 2 is shown one side frame 5 of the loom, the breast beam 6, the swinging lay 7 which carries the reed 8, the heddles 9, the warp threads 1 which are supplied from a drum 10, the binder threads 2 and 3 which are supplied from a drum 11 and the woven fabrix m.

are a pair of notched brackets 12 adapted to receive a transverse bar 13 (Figs. 3 and 4.) Mountel upon brackets projecting rearwardly from the breast beam 6 is a rock shaft 14 provided with a pair of hooks 15 and with an operating handle 16. When a sufiicient length of fabric has been woven in the regular manner and it is desired to form a course of wick loops 1 the loom is stopped with the lay 7 in its rearward position. The transverse bar 13 is then longitudinally introduced in front of the lay, below th binder threads 2 and 3 and above the wrap threads 1. The weight of the bar pulls down a suflicient length of each warp thread to permit the bar to be placed in the notches of the brackets 12, as shown in Fig. 4. The lay is then swung forwardly until the bar 13 is below the hooks 15, which normally occupy a raised position as shown by full lines in Fig. 4. The shaft 14 is then rocked by means of the handle 16, causing the hooks 15 to engage the bar 13, as shown in Fig. 3 and by dotted lines, in Fig. 4. As the lay swings rearwardly the bar 13 will be retained by the hooks 15 and the loops 1 will be formed as the lay swings forward for the next beat. It is desirable to have the loops retained during two beatsin order that they may be well bound into the fabric. Then, while the lay is forward, with the notched brackets 12 embracing the bar 13, the shaft 14 is rocked to raise the hooks 15 and release the bar 13, which will ride back with the lay. The loom is then again stopped and the bar longitudinally removed, after which regular weaving is again proceeded with until it is desired to form another course of loops, when the described operation will again be performed.

1 claim:

1. The combination, in a loom, of the swinging lay, a rod for depressing the pile warp threads, means for detachably mount ing said rod on the lay, and means for engaging and retaining said rod when the lay is at the forward end of its swing whereby said rod is caused to produce loops of pile warp thread at the back of the fabric.

2. The combination, in a loom, of the swinging lay, the breast beam, a rod adapted to be carried by the lay and to act upon the warp threads, and a retaining device mounted on the breast beam for cooperation with said rod to produce loops of the Warp threads at the back of the fabric.

v 3. The combination, in a loom, of the swinging-lay, the breast beam, a rod adapted to-be carried by the lay and to depress the Warp threads, a rock shaft mounted on the breast beam and having projecting hooks thereon, and means for swinging said rock shaft so as to cause its hooks to engage and retain the rod When said lay is at the for- Ward end of its swing.

In testimony whereof I have si ned my name to this specification.
